The idea to generate our pages tables from an array of memory ranges is very sound. However, instead of hard coding the code to create up to 2 levels of 64k granule page tables, we really should just create normal 4k page tables that allow us to set caching attributes on 2M or 4k level later on.
So this patch moves the full_va mapping code to 4k page size and makes it fully flexible to dynamically create as many levels as necessary for a map (including dynamic 1G/2M pages). It also adds support to dynamically split a large map into smaller ones when some code wants to set dcache attributes.
With all this in place, there is very little reason to create your own page tables in board specific files.
